But with the same light on both of the dual pixels of a set and a factor 2 difference between the pixels in a set, it should be'... neighboring A and B sub-pixels have a value of 4,000 and 8,000; ...'.

A pretty good way to confuse people.

The simple sum doesn't make sense to me.8192 + 16384 = 24576. Simply adding them, one is clipping at 10922 and the other at 5461, for a 14 bit into 14 bit result.And, even worse, with the bright pixel capturing a 50% brightness correctly as 8192, the sum would make it 8192 + 4096 = 12288, a 75% brightness.
